1972 Munich Germany Kitchen Tea Towel Calendar Olympic Summer Game

I bought this amazing lot from a former Olympic athletes. He was at a lot of games and started this collection around the 1980's. A lot of them were traded from athletes from other countries and quite a few related to the canoe kayak sprint he was involve in. I'm not exactly sure of the material. Either cotton or linen? Either way it is very soft. Size is approximately 15.5 inches long and 24.5 inches high
